[QUOTE="nasu, post: 6629343, member: 147320"] Well, if it is not constant then the capacitance is not constant. Similar discussions were started several times about resistance in Ohm's law. For electrostatics you have it actually easier. There are at least some cases where the capacitance is constant. So the definition is useful. Even if you cannot "prove" it applies to any single case, it is still an useful definition. Nothing to prove here. Same as for resistance. But for electrostatics, you have that potential of a point charge is proportional to the charge and the potential of any charge distribution can be calculated by superposition. Do you have an example of charge configuration with the potential depending in a nonlinear way on the charge size? If you do, wouldn't this contradict the superposition priciple? [/QUOTE]
